Cable from battery to sub.

[jocarl11]

Hi, Anyone know the best way to feed the power cable from the batter to the sub in the boot? The problem i'm having is gettin from the battery to inside the car without taking much apart?

Cheers Carl.

done it in the mk4, just find a suitable rubber grommet that passes through the firewall+ push it through where other wires go, then on the inside id run it along the plastics at the bottom of the doors
theres loadsa good audio install info on ukmkiv forum

Take your feed from the fuse box.

good point, on the mk4 theres a small fuse box on top of the battery with a place to put in a seperate fuse for the sub/amp exc but in mk3 may well be better doin it straight from fuse box although looking at the wiring around mk3 fusebox makes me  specially when theres a load of wires going nowhere/dodgily choped + spliced by x owners, oh well it hasnt caught fire yet

Ok i'll look into wireing from the fusebox Also need to replace the rear panel speakers, I take it they are 6.5?

Its a mk3 btw.

unsure about size but you should run the speaker wires away from your power supply to get the clearest sound or just shield the wires well

I ran my remote, RCA and power cable down the  passanger side of the car, under the sill trim (on the inside where the belt tensioner is) and up under the passanger footwell carpet and through a grommet on the firewall.

behind the glovebox is the perfect grommit for the wire (and it's for the alarm siren wiring which is located next to the battery)

The rear speakers and fronts are both 6.5".

As for routing, I did the same as khare, it's easy enough to do, more helpful to have a second person with you to help feed the wire through the firewall mind you. Make sure you run the speak cable down the other side of the car mind you, to cease any possibility of interference.

Don't forget to put an inline fuse between the battery and firewall!  Battery = 70amps...if that makes contact with any part of the metal of the car...well...arcs & sparks.  If your car goes up in a cloud of smoke, the insurance wont pay a penny when they find there is no fuse.
